How to implement my own theme/design to website?
Re: How to implement my own theme/design to website?
The way I do it is to build a design using a code editor - I use Dreamweaver, but it could be notepad for example. When it's how I want it I port it to CMSMS. I may be going about it the long way, but it works for me.
